Title: Study of transverse flow of kaons in Au + Au collisions at 1.23A GeV Author: Lukáš Chlad Abstract: The production and propagation of strange hadrons at the threshold energy are important probes of the in-medium hadron's properties and stiffness of the equation of state of nuclear matter. In this thesis, the transverse kaon flow at Au + Au collisions with kinetic beam energy 1.23A GeV measured with the HADES spectrometer is discussed. The motivation for such an analysis and the theoretical introduction are described first, followed by the characterization of the the individual parts of HADES spectrometer. The procedure to identify detected particles from the measured signals is introduced. Finally, the flow analysis and its results are presented. The differential directed and elliptic flow of kaons in measured gold on gold collisions is compared with published data and with kinetic transport model predictions. Keywords: relativistic heavy-ion collisions, transverse flow, kaon flow 1

HADES - STUDIUM ZMĚN VLASTNOSTÍ HADRONŮ
Chlad, Lukáš ; Kugler, Andrej (advisor) ; Soustružník, Karel (referee)
During the summer 2014, the HADES collaboration had the opportunity to measure pion collisions with different nuclei. These measurements were done with two objectives. The first being the investigations of hadrons with strange quarks and their behaviour at normal nuclear density. The analysis of this will concentrate specifically on φ meson and Λ baryon production. The focus on properties of baryonic resonances in the region of N(1520) and N(1535) formed the second objective. Special emphasis is put on beam line detectors which use different particle detection techniques. In particular, the scintillator based Hodoscope and diamond based Start detector will be discussed. There is also presented the analysis of π + p elastic scattering which is important for normalisation of the cross section of the reactions of interest. The measured elastic scattering yields are compared with dedicated simulations and previously published data. 1

Study of calorimetr to be used in heavy ion physics
Chlad, Lukáš ; Kugler, Andrej (advisor) ; Spousta, Martin (referee)
The purpose of this bachelor thesis is to apprise reader with the basics of mea- suring energy of particles with calorimeter which are being created in collisions on particle and heavy ion colliders. This research is mentioned in chapters 1 and 2. Another object is presentation electromagnetic and hadron calorimeters for accelerator complex GSI and FAIR in Darmstadt, Germany. There are men- tioned in particular moduls for ECAL and PSD calorimeter and also the read out electronic. The results and the description of modul testing are presented in chapter 3. 1
